IMPROVEMENT IN EYELETTING MACHINES.

SPECIFICATION.

Beit knownthat I, PHILANDER HARLOW, of Hudson, in the `county of Middlesex, and State of Massachusetts, have invented a new and-useful or improv'ed Machine for Setting Eyelets in Leather or other material; and do hereby declare the following to be a full, clear, and exact description thereof, reference being tothe accompanying drawings, making part of this specification, and which-w Figure 1 is a top view or plan, and A 1 y Figure 2 is a side elevation of the machine constructed in accordance with my' invention,

Figure 3is an under side view. i

-Figure 4, a vertical and longitudinalsection, and i Figure 5, a front end view`of the said machine.

Figure 6 is a plan, and p Figure 7, a section of the eyelet-hopper,or magazine, to be hereinafter described.

Figure 8 will be duly referred to.

Figures 9, 10, and 11 are face views of. some of the grooved disks, the same being hereinafter described.

In the drawings above mentioned, A denotes the table or frame of themachine, it being suitably formed for containing and supporting the-.operative parts. The driving-shaft of the machine is shown i .at B, it being suitably supported in bearings, a a, projecting downward from the operating bed, b. A goose-neck, c, rises from one end of the bed, b, and supports on its opposite sides two bent levers, c c', whose shorter arms extend into a. cam-groove, d, formed in the periphery of a disk, e, secured to the driving-shaft, the groove i being of the requisite form to so actuate the levers, c c", as to raise and `depress their longer arms, and also two sliders, ff', attached to the frontends of the levers, and working in bearings made in the head, g, of `the goose-neck, The slider fcarriesthe punch, n, and the slider f the eyelet-depressing die, o, each of whose operations willbc duly described. The mechanism for feeding the material along, and for setting the eyelet, may be thus described: A slider or carriage, D, is so applied to the under side of the bed-plate,'lrz, by means of dovetailed guides, L z, asto be i capable of slight reciprocating movements transversely of the, machine, this movement being et'ected by a grcoved arm, z', attached to the front end of a rocker-shaft, E, supported in brackets suitably applied to the frame of the machine (a stud frbm the side of the carriage, D, extending into the groove of the arnn) this rocker-shaft being actuated by a second arm, j, vmaking partof it, and extending into an eccentric groove, 7c, formedin the front face ot" a disk, F, fixed to the driving-shaft, B. The sliding carriage D and the arm t', should have an adjustable connection, in order to vary their relative Ypositions as circumstances may require. The `sliding carriage, D, carries a tubular slider, l, (which plays in a recess` m,4`formed in the carriage,)

the upper surface of this slider being properly formed for spreading or setting the eyelet in conjunction with the die, o; the slider or spreader, l, having a reciprocal vertical movement imparted to itby means of an arrn; p, jointed to it and tothe frame A, and"-which, in turn, is actuated by an eccentric groove, q, formed in thei'ront face of a disk,G, secured to the driving-shaft, the connection betweenV the slider l and arm p being a dovetailed groove and stud, as shown in the drawings.` Furthermore, the slider l carries an eyelet receiver nr carrier, .8, which slides freely within it, and which also has. reciprocating vertical movements impartedtogit by means of a second arm or lever, t, which. has a Asunken recessi` formed in it for receiving one end of a bange, applied to the receiver s by aset-screw, the oppos'ite end of the bar vsliding upon a supporting rod; or guide, w, `depending from the sliding carriage, "D, as sliown in ig. 4 of the drawings. 'The .lever t is actuated hyan eccentricgroo-ve, z, formed inthe disk G, and surrounding the groove q, a stud from the rear,side of thelever t, enteringthe said groove, 2:. l i

The mechanism for supporting the leather or other material to be suppliedwith eyelets,while undergoing the processof having thehole punched in it, consists of a plateyy, sliding in a dove/tailed groove formed in the upper surface of the operating bed, b, and which isoperatcd by a bent lever, z', applied to the under side of the bed and whose fulcrumis shown at z', the lever y receiving its proper movements by the agency of a; pitman, al, connecting its rear extremity with the shorter arm of lever c. The mechanism for .supplying the eyelets Vconsists of a recessed wheel, H, (see figs. 6 and 7,) having its perimeter formed with a series of eyelet-Lreceiving spaces, b1 b1, 8m., and attached to thelower .extremity of a vibratory arm or carriage, I, by a screw or bolt bz, passing centrally through it, and screwed into the carriage, I, and so. that it shall rotate freely thereon. The vibratory carriage is, in turn, supported on a standard, J, rising from the bed b, of the machine, ajnurnal froml this standard extending downward through the bed, and having v,an arm, cl, applied to it, a stud' or roller,

.cifrom the extremity of this arm, extending into a cam-groovle, d', formed in the perimeter of a disk, k,

applied to the driving-shaft, BQ The revolutions of the disk Ic will impart a vibratory movement to the carriage, I, upon its-journal. The. upper part of the carriage I has a hopper, L, formed upon it, for containing the eyelets, which are to be supplied toit promiscuously, a chute, el, leadingfrom the hopper to the recessedwheelf,` H, serving to conduct the eyelets thereto. This chutg is to bo so formed, with a horizontal trough and a verti cal opening or slot, as to cause the eyelets' to enter it and* advance towards the wheel H, with their smaller endsupwards, the eyelets being agitated within the hopper L by a vibrator-y brush, M. The chutee, in practice, `is

to be covered with a protecting plate. If considered desirable, an additional chute may be formed in the arII'tf`r or carriage, Lito render the supply of eyelets to the wheel H more certain, but in practice one will probably be found sufficient, The `hopper has a revolving sectoral cover, e, applied to its supply-throat, e, by a turning pin,f2, a spring-latch, gap`plied to the upper side of the hopper, and having a studiiponl its under side, tp. enter a h ole in the cover e2, serving to retain the said cover in position when closed, but'wlich will allow it, at 'the same time, to be opened. The supporting journal, iL', of the brush M, extends through the .bottom of the hopper, and is jointed to a forked arm,'z", which receives between its prongs the upper extremity of a vibratory lever, y", whose fulcrum is a recessed bearing, lc', made in the bed-plate, b, of the machine, the lever K being' duly operated by an arm, l', secured to the rear end of the driving-shaft. For the purpose of varying the relative distance of the depressing die from the punch, in order toV increase or diminish the distancepbetween the eyelcets after being set in the leather, the sliderfmay have a foot or block, m', applied to its lower extremity, in which a dovetailed channel, n', is. out, toreceive a corresponding shaped or dovetailed slider, o, to which the depressing die is secured by a male screw, o2, cut upon it, or by any suitable device which will allowlof its position being changed. The above-described adjusting mechanism is shown in 'cross-section, in iig. 8.0i' the drawings. The presser-foot for keeping the material tobe supplied with eyelets down upon the punching-plate, y, is composed of a bar, q', having a lateral extension, r1, to bear upon the material and press it down upon the plate, y, the fnlcrum bearing of this lbar being a convex project-ion, r2, extending upward from a sliding-plate, el, so applied to the bed-,plate b as to be capable of longitudinal adjustment with respect to the `punch and its supporting plate, y. The stationary fulcrum pin connecting the bar q to the projection r1, is shown at r3. The presserfoot, olr its part, rl, is raisedl while the material is fed along, by means of a rod, tl, extending through a slot, t2, .made in it, and whichyhas a thumb-nut, t3, screwed lupon its upper end, to bear upon the upper surface of the bar q. The lower end f this rod is jointed to the free end of a rockerarm, it", the other end o'f which is jointed to the frame of the machine, the arm u', (and with it the rod th) being depressed by theaction of a wiper, v', fixed upon the rear face of the disk, Gr, beforereferrcd to, and being elevated by the action of a plate.- spring, w, applied to the bed-plate, b, and extending under the rear end of the bar g', lsucll spring serving to keep the presser-foot down upon the material. The front end of the convex bearing, r1, which extends s omewhat inrear of the'path of movement of the punching-plate, y, is pointed, and serves asa gauge to guide the material while being operated upon. I i l' In operating with the above-describedfmaobine, we will suppose it to be in the positionas shown in the drawings, andthe hopper to besupplied with a desirable quantity of eyelets. The leather, or other material, is to be laid uponth'e bed-plate, b, and lthe driving-shaft put in rotation. On revolution of the driving-shaft, the groove vl, of thel disk e, will `so actuate the lever c as to depressthe punch, while simultaneously with this `action, the punch-supporting plate will be moved forward, and iinder the punch, by the action-of the bent lever, z, and pitman, a, operating with the, lever, c, and the punch be forced through the leather, the presser-foot, during this operation, remaining down upon the leather. While this operation has been going on, the recessed'l eyelet wheel, H, attached to the vibratory carriage, I, has been movedforward intol such a position, by its actuating mechanism before described, as to bring an eyelet contained in one of its recesses directly over the path' of movement of the receiver, '.s, and the receiver moved upward within the tubular slider, l, and into the eyelet by the action of the eccentric groove, a1, rocker-arm, t, and cross-bar, v. On continued revolution of the drivingshaft,the vibratory carriage, I, will be partially rotated upon its journal by the action of the cam-groove, In, and lever or arm, j, and moved rearward, and carry the recessed wheel away from its position with respect to the receiver s. this rearward movement of the vibratory arm, I, that revolves1 the wheel H on its turn-pin suliiciently to bring the nextvcontiguous recess into -the proper position forcarrying the eyeletover the receiver,

asby referring to the model, it will be seen that this is caused by the teeth forming the boundaries ofthe. recesses, u u, striking against the receiver while the rearward.y movement of the carriage is taking place,v thus` rendering the intermittent rotary motion automatic, o-selfacting, and requiring no specific mechanism to accomplish it. The groove d is of such a shape asto allow the recessed wheel to remain in its 'extreme' rearward position while the tubularslider, l, and receiver are being forced upwards and rearwards, and the eyelet carried` by them into thehole in the leather, which, by the previous revolution of the machine, was punched for..

4its reception, which w-'ill be accomplished by the action of the eccentric groove, q, arm p, and dovetailed'groove and stud before described, operating the slider to produce its vertical movement, and the carriage, D, operated" by the rocker-shaft, E, and its mechanism before described, producing its rearward or transverse movement, the receiver, s, in the mean time serving to confine the eyelet in position upon the spreader or slider. As the driving-,- shaft, continuing to revolve the spreader by the action ofthe cam-groove iipon the lover, el, will 'be forced' downward towards the setting die; andxat the same time the receiver, s, will retreat -froinrbefore it, andallow the eyelet to be spread at its'upper part over upon the leather, and be set thereto. It will. be seen that\the receivers, Aand surrounding sleeve or sheath, l, have several distinct and importantA functions. The nature of their construction and arrangement is'such that they are each capable of horizontal andl'vertical reciprocating motion, as above explained. When the punch, n, is in the position shown in g. l, the receiver rod, s, has been 'pushed by its actuating mechanism out from the sheath, l, so as to be inserted through and hold one of the eyelets contained inthe wheel, H, and it is just underneath the punch, n, the slide-plate?! intervening between them. Now, when the main shaft, B, is revolved, the intervening reciprocating plate, y, is moved back, and as soon as it is fairly out of the Vway, the upward vertical movement of the sheath, l, and-receiver, s, begins. They move up towards the punch, n, which, as they advance, is proportionably withdrawn -from the punched leather, or other material, until the projecting end of the receiving rod, which, it will bei remembered, also carries the eyelet, as above mentioned, fits in and is inserted through the hole punched in the leather by the punch, n at the same time the presser-foot, r', is lifted from the leather. Everything4 isnow in readiness for the feeding forward of the leather to the setting" mechanism. Up'on continuingthe rotation of the driving-shaft, the horizontal motion of the sheath and receiver rod begins. By the arrangement of their actuating mechanism, as above explained, they arc moved horizontally toward the setting die, the receiver rod, s, carrying with it the leather through which itl is' inserted, until it brings the hole formed thereinby the punch, 1t,directly under the die, o. Here the horizontal motion of the sheath and receiver rod ceases, and their vertical movement again begins. `The setting die, o, is now depressed by the action of its operative mechanism, and, as it approaches the leather, the receiver, s, is retracted therefrom, until v the die takes the place formerly held by the Vreceiver rod,v being inserted through the punched leather and eyelet, which are now pressed firmly against the sheath, l, the top of which forms a die-plate, as before explained.; and by the resistance of the latter against the` pressure of the setting die, o, the eyelet is forced up through the punched hole and is set to the leather. The presserfoot, r', at the same time comesdown and presses firmly upon the leather, so that by the continued rotation of the shaft B, the die o is withdrawn' from the eyelet-hole without diiiieulty, and the leather is ready to be again punched. It will be seen that the reciprocating motion of the sheath or slider, and receiver rod, is alternately horizontal and vertical, while in the latter movement they are actuated successively and, in a measure, independently of each other. By this arrangement I aml enabled to use the receiver rod, s, not only to hold and centre the eyelet, but to feed the leather from the punch towards the setting die, and `also to centre or to place ythe punchedhole in its proper position in relation to the die, and to adjust the eyelet to the hole preparatory to its being sct" therein by the action of the die and matrix.

Having described my invention, and the manner in which the-same is or may be carried into eifect, what I claim, and desire to secure by Letters Patent, is' as follows: l

I. I claim the combination. with the setting die of an eyeletting machine, of an eyelet receiving-rod,and surrounding sheath or die-plate, and mechanism for actuating the same, under the arrangement and for operation as herein described, so that the said receiver rod shall constitute the means whereby the eyelet is adjusted to the punched leather, and the leather fed forward to the setting die, substantially as set forth.

II. In an eyeletting machine, I claim the combination, with the eyelet receiver rod'and surrounding sheath or die-plate, as described, of the setting die and punch forming the eyelet-holes, under such an arrangement that, by the action of said punch, receiver rod, sheath, and setting" die, the leather or other material operated on shall be alternately punched, fed forward to the setting die, andv stamped with eyelets, substantially as herein shown and described. j

III. In an eyeletting machine as described, I claim the combination, with the punch for forming eyeletholes, of a reciprocating or sliding plate for sustaining the leather under the action of said punch, `arranged and operating substantially in the manner and for the purposes set forth.

IV. I claim the adjustable presser-foot and its actuating mechanism, as herein described, for producing an intermittent pressure upon the leather or other material operatedon by the punch and eyelet setting die,- substantially as and for the purposes set forth.

I claim the mechanism for feeding the eyelet, as herein described, the same consisting of chopper andv vibratory arm provided with one or morechutes for conductingand holding the eyelets, and a wheel or disk, in the periphery of which, recesses are formed for the reception of the said eyelets, the whole being combined and operating substantially in the manner shown and specified.`

VI. I claim the combination of the above-described eyelet-feeding mechanism with the eyelet receiver rod and surrounding sheath, under such an arrangement that, by the motion of said vibratory arm, the eyelets held in the recessed Wheel may be fed to the said receiver rod, substantially as herein shown and described.- i

VII. I .claim the combination, inan eyeletting machine, of mechanism for punching, feeding, and holding the material operated on, and for feeding and setting the eyelets to the same, under the arrangement, and for operation substantially as herein shown and set forth.
